Hi,

I wanted to write a simple program using class (object oriented). I've
attached my helloClass.cpp and also Makefile. after runnig make I get
below errors.
I think:
1. it is the problem of using c code in c++
2. I've used extern "C" in helloClass.cpp
3. Should I recompile the DPDK from source with gcc -c argument for
compatibility with g++?

Thanks in advance.

g++ -c  helloClass.cpp
-I/home/hamid/dpdk/dpdk-1.5.1r1/x86_64-default-linuxapp-gcc/include
g++ helloClass.o
